Leads me to a funny story. A girl in my department let a professor drive
her car. When she got it back the parking lights kept flashing. She did
everything she could think of and then finally made an appointment to take
it into the dealer. She drove it for a week and a half blinking the whole
time. She took it to the dealer, the service manager walked out looked at
then turned off the hazard flashers. All fixed..... He got out and walked
away not saying a word but you know he was laughing in side....
The last time this happened to me I had miss wired the light plug for my
trailer. I had accidentally grounded one of the wires and the draw was
making the flasher switch work... You may want to determine which flasher
is working. You have two, one for the turn signals and one for the hazard
flashers. This is easy to do just pull each flasher and see when it stops
clicking. Then you will need to see what is drawing power in that circuit.
I have double checked and the turn signals front and back only work when the
signal arm is activated. Same thing with the hazard lights. But with the
lights all dark and the switch arm in center position I still get the sound.
It makes me feel like I'm riding with my grandparents!

It probably has nothing to do with your flashers or turn signals. I had the
same issue, years ago, with my '99, but it stopped doing it before I had a
chance to trace it down.
You'll just have to dig into it and find the relay that's making the noise,
and replace it. If that doesn't fix it, look for a bad ground.
